Abstract
Micro-electro-mechanical circuit for 30 W high power Piezoelectric Transformer (PT) with modeling and characterizations to be used in Electronic Ballast (EB) is designed for the first time. Significant parameters at 77.6 KHz of frequency and 87 mA of low input current result in excellent efficiency of 84% and high voltage gain of 0.9 for 30 W high power for electronic ballast, which can save much energy and be a great domestic asset. Our proposed PT circuit with proper optimization of circuit parameters can also enhance further power and efficiency for future high power applications
